How to control the ubuntu system in win10 through ssh

I wrote an article "2019-09-15-How to open the ubuntu system in win10" earlier, and some students asked if I could remotely control this ubuntu via ssh. Although it is easy to open a ubuntu window on win10, you can also open multiple windows to achieve multiple terminals, but if you can control ubuntu through ssh, you can open multiple terminals more conveniently, or you can just use this ubuntu as one It is indeed a requirement to use a server in a linux environment. Today, I will write an introduction to the realization of this requirement.

1. Install ssh server

The ubuntu18.04 version is installed by default, and this version comes with ssh service by default.

Check whether the ssh service is installed:

ls /etc/ssh/sshd_config

If the file exists, it is already installed. If it does not exist, execute the following command to install:

sudo apt-get install openssh-serve

2. Start ssh server

• Check that the ssh server is running

Execute the following command to check whether the ssh server has been started.

ps -aux | grep ssh

If there is the following line /usr/sbin/sshd, it means that the ssh server has been started.

efonfighting@DESKTOP-ARKC8D1:~$ ps -aux | grep sshd
root        640.00.019464800?        Ss   01:030:00/usr/sbin/sshd
efonfig+680.00.0148041204 tty1     S    01:040:00 grep --color=auto sshd

If only the following one is printed, it means it is not started.

efonfighting@DESKTOP-ARKC8D1:~$ ps -aux | grep sshd
efonfig+430.00.0148041204 tty1     S    01:010:00 grep --color=auto sshd

• Modify sshd configuration
  Open /etc/ssh/sshd_config and modify the following items
  Port 22, ``ListenAddress 0.0.0.0 # Uncomment'' #StrictModes yes # Comment ``PasswordAuthentication yes # Allow password login
• If it is SecureCRT, I encounter the problem of “No firewall'None' is found in the database

Find "Global Options" → "General" → "Configuration Folder", create a new FireWalls folder under this folder, and create a blank file without .ini in the FireWalls folder.

• Start ssh server

At this time, you need to execute the following command to start the ssh server:

sudo service ssh start

After execution, a firewall problem will be prompted, just click Allow. At this time, our ssh server has been successful.

• Open port 22 of the firewall

3. Access ubuntu in win10 through ssh

At this time, we enter ifconfig and ipconfig in the ubuntu window and the windows cmd window respectively to check the IP address.

This is if we want to access the built-in ubuntu of win10 locally, we can directly access 127.0.0.1 through the user name and password, instead of manually opening an ubuntu window. It's really convenient.
